Plastics and limited quantities of mixed general waste can be effectively repurposed into new products for the built environment through additive manufacturing. Plastics and hard waste have multiple pathways for providing a new useful life: upcycling, downcycling, and energy extraction. This project collects and proposes the most promising options for pre-farm gate waste to find a new useful life in on-farm and commercial products. Example products include building and architectural materials as well as consumer products. The proposed options are sourced from proven research around the globe and consider the economic, environmental, and social impacts to provide a holistic solution the suits modern agribusinesses in Australia.
